Oh yeah, and I did listen to them. If I remember correctly, the first song was performed well, but I just hated the song, and the second song(Howl's) was the most amazing song in the world (nice footwork) but there was quite a few blunders that were too apparent, don't stop to redo the measure, just continue.
I would point out that you would continue on as if the mistake never happened (most would not notice) but people very acquainted with the song would notice. but to keep the tempo going while even being shocked by those mishaps would be even more impressive.
I must say I am jealous of you memorizing the whole song, I would do it, but I'm lazy.
